BOTaXIOAL EXCHANGE’ CEUJt, 
Agrimonia odor at a, Sent by Rev. W. H. Purchas from 
Lydney, Gloucestershire. Detected last Summer by the Rev. W. 
W. Newbould on hedge banks near Thirsk, N.E. Yorkshire, and 
in woods near Staward peel, Northumberland. It had previously 
been gathered in the latter county in two stations (Kyloe crags near 
Belford and in Simonburn dene in North Tynedale) by Professor 
Oliver and Mr. W. II. Brown. This adds two provinces and one 
subprovince to its area as given by Mr. Watson. 
Rosa tomentosa. Sent by Mr. Briggs, from near Landulph, 
in Cornwall, and from another station in the North of the same 
County. 
Rosa micrantha. Sent by Mr. Briggs from various stations 
near Plymouth, some in Devonshire, and others across the Cornish 
boundary. A curious variety from near Bickleigh has globose 
fruit and naked peduncles. 
Berberis vulgaris. Mr. Briggs sends a specimen, with which 
he writes “ It is from a Cornish station where I think it likely to 
be indigenous. It grows in two or three spots among bushes that 
fringe a low cliff or bank above St. John’s lake, an inlet from 
Hamoaze, and so connected with the sea.” 
Hybrids between Galium Mollugo and verum. Mr. Briggs 
sends from the neighbourhood of Plymouth two forms of Galium 
with which he writes, “ The first, which I obtained on the edge of a 
cliff between Wembury and Bovisand on the first of July is I doubt 
not the G. verum var. oclirolcucum of English Botany, 3rd edition. 
It is, I think, a hybrid. G. verum abounds on the cliffs where I 
found it, and G. elatum was growing near it. The other I think 
also a hybrid between the same two species, but partaking more of 
the characters of elatum. I found it on the 29th of June, growing 
on a bank by the side of the road between Plymouth and Saltash; 
There was only one root, close to which was a mass of G. elatum 
and a patch of G. verum." The characters of these two plants are 
as follows. 
G. vero-elatum. Stems about 
a foot long, slender, scarcely 
thickened at the nodes, pilose 
throughout. 
Leaves about eight in a whorl 
and fully deflexed upon the main 
stem, linear-subulate with revo- 
lute edges, the largest three- 
eighths of an inch long by not 
more than half a line broad at 
the widest part, the texture thick, 
G. elato-verum. Stems one 
and a half to two feet long, much 
stronger than in the other, con- 
spicuously thickened at the nodes, 
pilose throughout. 
Leaves about eight in a whorl, 
deflexed upon the main stem, 
linear-obovate mucronate, broad- 
est at two-thirds of the distance 
from the base to the apex, the 
largest three-eighths of an 
inch long by nearly a line broad,
